Boosts all Major Networks (+ Virtual Ones)

This unit can boost available signal for O2, EE, Three, Vodafone & all Mobile Virtual Network Operators - you can find a full list here.

 

The CEL-FI CONNECT C41 can only boost one main network at a time - if you are wanting to boost more than one network at once then please see the CEL-FI QUATRA 4000e.

 

Each C41 system will amplify the signal of both the main AND all hosted networks, on 3G, 4G and 5G* (*5G subject to coverage) simultaneously. If configured for O2 it will also work for giffgaff, Sky Mobile, Tesco Mobile etc.

Future Proof - Your Investment is Protected

Whilst the CONNECT C41 can only boost one main network at once, unlike other units you don’t need to buy a new unit if you change network in the future.


Simply use the Wave app (which you will need to download during installation) and you can easily change the settings within a few seconds.

What is this Model Suitable For?

This model is designed for homes where you wish to boost the signal in a single room of the property and there is good signal next to a window. You will benefit from this model if you can stand next to this window and use your phone with no problem.

 

If the signal needs to be improved throughout the whole property then you should consider the GO G41 or GO G41 with external antenna if there is no signal inside.
